Title: Emission vessel for high-pressure discharge lamp
Inventor: MIYAZAWA SUGIO
IPC: H01J61/30
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce the corrosion of frit glass caused by an illuminant material when emission vessel is used in a high pressure discharge lamp. SOLUTION: Atrunk part 1 forms the discharge space on its inside and has opening parts for inserting electrode member inserting parts 3a, 3b at both ends of the discharge space. The electrode member inserting parts 3a, 3b have fins 6a, 6b arranged between inserting parts 4a, 4b and exposed parts 5a, 5b respectively. Since heat is radiated from the vicinities of fins 6a, 6b, liquefaction of an illuminant material in through holes of electrode member inserting parts 3a, 3b is accelerated, the liquefied illuminant material is solidified before it enters an exposed part in the inner space of the trunk 1 of the frit glasses 11a, 11b. The illuminant materials 12a, 12b solidified in this manner are attached to the inside of the through holes of the electrode member inserting parts 3a, 3b.  This reduces the corrosion of the frit glasses 11a, 11b caused by contacting of the liquefied illuminant materials with part the exposed in the inner space of the trunk 1 of the frit glasses 11a, 11b.

IPC: H01J37/317
Filed: 1986-04-09
Abstract: PURPOSE:To enable beam lithography to be performed with ion implantation densities varied continuously, by controlling a frequency of a scanning clock applied to a deflector based on the upper and lower limits of densities of ions to be implanted, with respect to a single pattern. CONSTITUTION:A scanner 24, receiving graphic data from a data transfer controlling circuit 23 and data on upper and lower limits of ion implantation densities from a dose memory 25, outputs a control signal so that ions are implanted to form a pattern as indicated by the graphic data while the density of the ions are continuously varied within the range between the upper and lower limits of the ion implantion densities. Clock data are outputted sequentially from the scanner 24 and given to a frequency demultiplier circuit 27 as control signals. The frequency demultiplier circuit 27 thereby demultiplies the inputted clock in accordance with the inputted control signal and outputs a scanning clock having a frequency corresponding to the control signal. A deflector 28 deflects an ion beam in accordance with the inputted scanning clock so that the ions are continuously implanted to print the pattern on the chip 29.
